Abstract
A control system (100, 200) for a vehicle suspension system of a vehicle (900) is disclosed. The control system is configured to: determine that the vehicle is operating in a precondition state in dependence on an actuator power supply status; and output a first damping control signal to an adaptive damping system of the vehicle in dependence on the determination. The first damping control signal is configured to cause the adaptive damping system to activate a first damping control mode in which a predetermined level of damping is provided to the vehicle.

A control system for a vehicle suspension system of a vehicle, the control system comprising one or more controllers, the control system configured to:
- determine that the vehicle is operating in a precondition state in dependence on an actuator power supply status;
- and
- output a first damping control signal to an adaptive damping system of the vehicle in dependence on the determination;
- wherein the first damping control signal is configured to cause the adaptive damping system to activate a first damping control mode in which a predetermined level of damping is provided to the vehicle, and
- wherein the precondition state includes at least one or more of:
- determining that an electrical energy storage module is connected to the actuator power supply;
- determining whether the actuator power supply is charged to a predetermined charge threshold;
- outputting an indication to one or more actuators that the actuator power supply is in operative communication with the electrical energy storage module;
- and
- determining that no faults are detected in any component of the vehicle suspension system.
A method, comprising:
- determining that a vehicle comprising a vehicle suspension system is operating in a precondition state in dependence on an actuator power supply status;
- and
- outputting a first damping control signal to an adaptive damping system of the vehicle in dependence on the determination;
- wherein the first damping control signal is configured to cause the adaptive damping system to activate a first damping control mode in which a predetermined level of damping is provided to the vehicle, and
- wherein the precondition state includes at least one or more of:
- determining that an electrical energy storage module is connected to the actuator power supply;
- determining whether the actuator power supply is charged to a predetermined charge threshold;
- outputting an indication to one or more actuators that the actuator power supply is in operative communication with the electrical energy storage module;
- and
- determining that no faults are detected in any component of the vehicle suspension system.
